To test the effectiveness, 1000participants were randomly selected with 500 people getting the shot and 500the nasal spray. Of the 500 people were treated with the shot, 80 developed theflu and 420 did not. Of the people who were treated with the nasal spray, 120people developed the flu and 380 did not. The level of significance was set at.05. The proportion of people who were treated with the shot who developed theflu = .16, and the proportion of the people who were treated with the nasalspray was .24. The calculated p value = .0008.Describe the research question for this experiment. What were the null and alternative hypotheses? Were the results of this test statistically significant? If so, why were they significant? Describe the difference between practical and statistical significance
